How to Have a More Useful Conversation with an Arborist When You Think a Tree Might Be Dangerous
If you have ever tried to describe a tree problem over the phone to a tree service and felt like you were not quite conveying what you were actually seeing, this is for you. Getting from "I think something might be wrong" to an arborist who can give you a useful initial read takes some specific information. Here is a practical guide to gathering and communicating it.

Step 1: Walk the Tree Before You Call
Spend 15 minutes walking around the tree and taking notes. Arborists cannot see your tree from a phone call, and the more specific information you can provide, the more useful their response will be. You do not need technical vocabulary. Plain descriptions work fine if they are specific.
What to look for and write down:
At the base: Is the bark firm when you press it, or does it yield? Are there mushrooms or fungal growth directly on the trunk or root flare, or just nearby in the lawn? Is the soil raised, cracked, or heaved on one side of the trunk? How close is the tree to the nearest structure?
On the trunk: Are there any cracks or gaps you can see in the wood itself (not just the bark)? Is there any visible opening or cavity? About how far up the trunk do these start? Does the crack appear to follow the grain of the wood, or does it go across it?
At major junctions: If the tree splits into two or more main stems, describe the junctions. Are they tight V-shapes or wider angles? Can you see a dark seam or crease running into the crotch between them?
Canopy condition: Are there large dead branches (bare while surrounding branches have leaves)? Are there any branches that appear to be hanging at odd angles or resting against other branches?
Lean: Does the tree lean? In which direction? Has it always leaned that way, or did you notice it getting more pronounced recently?
Step 2: Take Photographs
Photograph everything you described. Ground-level photos of the trunk base. Close shots of any cracks or cavities. A wide shot from 30-40 feet away that shows the whole tree and its lean angle. A photo of the junction between main stems if the tree has co-dominant structure.
If you have any older photographs of the tree, even from a phone's camera roll going back two or three years, include those. Arborists can see changes in lean, canopy dieback progression, and junction condition over time if you have the comparison.
Step 3: Know Your Target Zone
When you call, the arborist will ask what the tree is near. Have that information ready. Which structures are within the tree's height in any direction? Which direction does the tree lean relative to those structures? Is there a frequently used area, a driveway, a neighboring property, or a utility line in the failure path?
This information directly affects how the arborist categorizes the urgency of your call. The same structural defect on a tree in an open yard and a tree over a garage are different risk conversations. Telling them the target information upfront saves time.
Step 4: Be Honest About When You First Noticed It
Arborists want to know the timeline. Did this crack appear after the last storm, or has it been there for years? Has the lean increased recently, or is it stable? Are the mushrooms new or do they come back every season? Knowing whether a problem is new or long-standing helps the arborist understand whether the situation is actively progressing or has reached some stable state.
"It has always been like that" is useful information if it is accurate. "I noticed it last week" is different information with different implications.
Step 5: Ask the Right Questions When They Get There
When the arborist visits, you are having a professional assessment, not just getting a quote. Use the time to understand what they found, not just what they recommend.
Ask: What specific defects did you find, and where? Can you show me what you are looking at? What does the structural significance of this defect mean for this particular tree? What would change this situation from routine to emergency? What are the signs I should watch for that would mean I should call you back sooner?
The International Society of Arboriculture emphasizes that a good hazard assessment includes an explanation of the findings, not just a recommendation. If you do not understand what the arborist found or why they are recommending what they are, ask them to explain.
Specific Language That Helps
A few phrases that translate well over the phone:
"There is a crack in the trunk that I can probe with a screwdriver" is more useful than "there are some cracks in the bark."
"The two main stems have a crease running into the junction rather than a ridge" tells the arborist you are describing included bark, which is a specific finding.
"The soil on the north side of the tree looks raised, and the tree leans slightly south" gives them a picture of a root plate under stress.
"The mushrooms come back every fall at the base of the trunk, not in the lawn generally" indicates recurring fungal activity at the structural level.
For Monmouth County Homeowners
If you are looking for a local certified arborist for this kind of assessment, Hufnagel Tree and Middletown Tree Service both work throughout the area and handle both emergency evaluations and routine assessments. Either one can walk through what you described and give you a specific read on what you are actually dealing with.
The Rutgers Cooperative Extension has resources on tree health assessment that are calibrated for New Jersey conditions, which is useful context when the tree issue involves disease or pest-related stress alongside structural concerns. The Morton Arboretum has the most accessible public resources on structural defects specifically if you want to understand more about what an arborist is likely to find during the visit.

After the Assessment: Following Through
The most common outcome of a hazard assessment that results in a "routine removal" recommendation is that the homeowner puts it on the list and the tree stays on the property for another two or three years. Sometimes that is fine. Sometimes the tree gets worse faster than expected and the routine removal window closes.
If an arborist tells you a tree should come down but is not an emergency right now, ask what specific changes would convert it from routine to emergency. Get that in writing or in a follow-up email. Set a calendar reminder to check those specific things every three months. If you notice any of them, call back rather than waiting for the next scheduled appointment.
The goal of the assessment conversation is not just getting an answer for today but establishing a framework for how you monitor the situation going forward. A good arborist will give you that if you ask for it directly.
